Application med September 11, 1922. Serial No: 537,605.

To all whom it may concern; Be itknown thatl, MARTIN GERBER, citizen of the United States, residing at Iowa City, in the county of J ohnson and State of Iowa, have invented certain new and useful Improvements in Radiator Repair Machines, of which the following is a speclfication.

This inventionrelates to radiator repair machines. More particularly, it belongsto that class or type of work holders that are designed especially to receive the radiators of. automobile motors after the radiators have been detached, and to support the radiators in various positions for convenience ofmaking repairs. This invention also belongs to that class of repair stands which are provided with a tank into which the radiator may be lowered to detect any leaks requiring attention.

The object of this invention is the production of an apparatus of the nature stated comprising parts of special construction and arrangement whereby it is believed an unusually strong easily operated, cheap and useful adjunct to a repair shop is provided for the purposes described.

In the accompanying drawings illustrating the construction and arrangement of the Various parts ofthis invention, Fig. 1 rep resents a front view ofall parts assembled,

portions being broken away to disclosethe interior of the tank, Fig, 2 is a side view,

with portions broken away to show internel members. Fig.3 is a front view of one end of the drip trough showing its supporting. bracket permitting it to'be slipped in and out offposition.

same part.

Considering the drawings, the supporting structure or stand has the legs A and a,

' and'a rectangular top B, provided with an inner portion 2 upon which the upper side of the tank C is turned over as illustrated. Transversely below the tank is the rocking Fig. 4L is atop plan; view. Fig. 5 is avertical section. of one side of the turntable ring and of the vertically movable frame carrying the ring, with the rollers providing for the horizontal revolu-' tion ofthe ring. Fig. 6 is a front view of shaft D,having a foot lever d in convenient position, and anupwardly extending catch blade The blade E passes upwardlythrough' the plate F having a lug' for engaging the 4 .14, provided with spaced notches e,

notches, and the notches and lug -mayv,be disengaged by pressure of the foot upon the foothold 71 arranged immediately above the foot lever (Z. The lug plateF has a'slotvG for the passage of the curved blade E, an'd the blade has a pivot gconneoting it with the foot lever. It will be noted thatthe notches c are fashioned toprevent the blade E from risingthrough the slot G whenthe notches and'lug of plate F are disengaged, andthe... reason for such construct on .1s that the welght of the radiator being worked upon -would tend to raise the foot lever, as hereinafter more fully explained. To balance in part the weight of the sustained" radiator, the weight H is introduced. it is carried adjustably upon the arm it which is secured to i the transverse rock shaftl).

As best illustrated in 2, thereis attached to the rock shaft/D a crank armJ,

that has apivotal connection-with'a'rod if which has in turn a pivotal connection with the vertically reciprocatlng post or tube K,

passing o -through the cylindrical guide 7::

erected upon the top B-of the stand. Itwill be understood that, as illustrated there is a crank arm such" as explained, with, a. con

necting rod, and guided'reciprocating tube on the other side of the machine. construction and operation of these parts are in all respects the same. The functionof the reciprocating tubes su ohas K is to raise and lower a movable frame L, with which the tubes are connecte'd'by vertical rods such as rodM, passing through the guide'm,*and"in i 'clmed braces N, and '97,, best shown in Fig.

,"l-he frame L is constructed to enter the tank,

and .it carries a turntable ring 0. The ring 1s prov1ded with cross-pieces or bridges and Q, as best. shown mIF g. r iWhich-are,

revoluble upon the su pportig rollersR', and

the workr ests, and the ring is horizontally the retaining or side rollers r,.the latter be- I vdirectlysupported by the frame L, and

the former by a block S attachedtothe Y framej There may be any number of sets of I rollers, In practice there are ordinarilv eight sets as'delineated, 1

1 At the sides and towardsthe front of the top Bof the stand are erectedftheposts or tubes T, one'on' either side'freinforced' by? the inclined braces t. These posts carry a vertically adjustable horizontal bar U, that may be supported in one or more different positions by pins such as the pin a engaging pinholes in the posts T. The bar U extends transversely above the frame and turntable, and at its ends is provided with the straps V and Q) which encircle the posts. The bar may be attached to a radiator to additionally hold the same in a desired position. It is believed to be clear that if-the bar U is thus attached to radiator, the same may still be given a limited up and down movement, provided the pins a are removed from the pinholes.

At the top, the posts or tubes T are bent in a forwardly direction, and each is attached to an upper cross bar TV. This is a stationary bar. lit supports the reflector c by which the light of the lamps shown in Figs, 1 and 2may be directed downwardly into the tank (J, This invention is not intended to be restricted to the reflector or number of light bulbs illustrated, and the reference letter 0 will be understood to designate a lighting device of any desired construction and arrangement for the purpose.

In addition to the lights, the bar TV supports the lever w best shown in Fig. 2, and the lever is adjustably held in either of a number of different positions by means of the finger catch X that engages the notches in the quadrant a: suitably arranged. The rear end of the lever 10 is connected with the lighting device Y by the cords 7 and the light Y may be raised or lowered to illumihate different portions of a radiator upon the turntable.

To catch water fallin from the top B of the stand, there is usually provided a drip trough Z, removably held in angle brackets The trough may be slipped out and cleaned at any desired time. In practive the trough Z is usually placed in communication with'the tank C by means of the drip tube L shown in 2.

In the operation of this invention, assuming a radiator to have been placed upon the cross-pieces P and C; of the turntable ring, it will be understood that by operating the foot lever the ring and its load may be lowered into the tank (J to detect leaks in the customary manner, and by suitably engaging the notched blade E with the lug plate F the radiator may be supported within the-tank. it will also be noted that in the tank or out, the turntable may be revolved to bring any portion of the radiator within sight or reach, and if need be the interior of the tank may be illuminated by the light from the reflector c mentioned. To render the labor of raising and lowering the radiator easier, the balancing weight-s H have been introduced.

In the drawings accompanying this application the vertically reciprocating member K, and the side posts T are shown as being formed by tubes and tubular connections, but it is not intended to confine this invention to the use of tubular parts.

Having now described this invention and explained the mode of its operation, what I claim is 1. In a radiator repair machine, the combination with a stand, of a tank carried by the stand, a frame constructed to enter the tank, means for raising and lowering the frame and for holding it in intermediate positions, and a turntable ring provided with cross-pieces'and carried by the frame and movable with the said frame into and out of the tank.

2. in a radiator repair machine, the com bination with a stand, of a tank supported by the stand, a frame constructed to enter the tank, means for raising and lowering the said frame and for holding it in intermediatepositions, a table carried pivotally by the frame and movable with it, and a vertically adjustable bar arranged above the said movable frame.

3. In a radiator repair machine, the 00-, bination with a stand of a tank supported by the stand, a frame constructed to enter the tank, means for raising and lowering the said frame and for holding the same in intermediate positions, a. turning table pivotally carried by the said frame and movable up and down therewith, and means extending over the said frame and carried by the said stand to which a radiator may be fastened to be worked upon.

4. In a radiator repair machine, the combination with a stand, of a tank supported by the stand, a frame constructed to enter the tank, means for raising and lowering the said frameand for holding the same in intermediate positions, a turning table pivotally carried by the said frame and movable up and down therewith, and adjustable lighting means whereby lights may be directed upon different parts of" a radiator borne by the said table.

5. In a radiator repair machine, the combination with astand, of a tank supported by the stand, a frame constructed to enter the tank, means-for raising and lowering the frame and for holding it in intermediate positions, the said means including Vertically reciprocating posts provided with inclined braces connected with the said frame to hold the frame horizontal, a turntable carried by the frame and movable with the frame into and out of the said tank, and a vertically adjustable support carried by the stand and extending over the turntable.
